Custom Engineering Capability

Engineering Cable Structures for Demanding Applications

Every cable can be tailored in conductor structure, insulation system, shielding, 

armouring, and jacket design to meet specific electrical, mechanical, and environmental 

requirements.

With over 1,000 cable variants developed, RouLine engineering team works closely with 

customers to create cable designs based on their application conditions, installation 

methods, and system requirements.

From conductor configuration and electrical performance to mechanical protection and 

environmental resistance, we provide customized cable solutions designed for each 

customer's specific operating environment.

Cable Materials & Construction Capability

Every custom cable starts with the right material and construction

RouLine selects conductor, insulation, shielding, reinforcement and outer jacket materials according to the electrical, 

mechanical and environmental requirements of each application. 

Our material portfolio includes PUR, PVC, PTFE, FEP, PFA, PVDF, silicone, XLPE and LSZH compounds, enabling cable designs 

for demanding environments requiring flexibility, abrasion resistance, chemical resistance, temperature performance and 

long service life.

Materials are sourced from qualified suppliers, including established global material manufacturers, and evaluated 

according to the requirements of the finished cable design.

Manufacturing Process & Factory Environment

Flexible Manufacturing for Specialized Cable Designs

Our manufacturing process is built around the specific construction and application of each cable. From material preparation and 

insulation extrusion to cabling, shielding, reinforcement, armoring, and final sheathing, production parameters are adjusted to 

meet requirements for flexibility, mechanical strength, temperature resistance, chemical exposure, and demanding operating 

environments. Our factory supports both customized cable production and small-batch manufacturing, with dedicated 

equipment for different cable constructions.                                                                                                 View Cable Gallery →

Testing & Inspection

 Testing for Electrical, Mechanical & Environmental Performance

RouLine cable testing equipment supports routine and project-specific inspection throughout the manufacturing process. 

Depending on cable construction and application requirements, testing may include electrical performance, insulation, continuity, tensile strength, environmental resistance, and dimensional inspection. Test methods and acceptance criteria can be adapted to the cable specification, applicable standards, and customer requirements. This testing process helps verify cable performance and manufacturing consistency before delivery.                                                                  View More Equipments →
